OcteonTx2's next gen platform the CN10KB has RPM_USX MAC which has a
different serdes when compared to RPM MAC. Though the underlying
HW is different, the CSR interface has been designed largely inline
with RPM MAC, with few exceptions though. So we are using the same
CGX driver for RPM_USX MAC as well and will have a different set of APIs
for RPM_USX where ever necessary.
The RPM and RPM_USX blocks support a different number of LMACS.
RPM_USX support 8 LMACS per MAC block whereas legacy RPM supports only 4
LMACS per MAC. with this RPM_USX support double the number of DMAC filters
and fifo size.
This patch adds initial support for CN10KB's RPM_USX MAC i.e registering
the driver and defining MAC operations (mac_ops). Adds the logic to
configure internal loopback and pause frames and assign FIFO length to
LMACS.
Kernel reads lmac features like lmac type, autoneg, etc from shared
firmware data this structure only supports 4 lmacs per MAC, this patch
extends this structure to accommodate 8 lmacs.

Most of the code in CGX/RPM driver assumes that max lmacs per
given MAC as always, 4 and the number of MAC blocks also as 4.
With this assumption, the max number of interfaces supported is
hardcoded to 16. This creates a problem as next gen CN10KB silicon
MAC supports 8 lmacs per MAC block.
This patch solves the problem by using "max lmac per MAC block"
value from constant csrs and uses cgx_cnt_max value which is
populated based number of MAC blocks supported by silicon.

Make MTU configurable on KSZ87xx and KSZ88xx series of switches.
Before this patch, pre-configured behavior was different on different
switch series, due to opposite meaning of the same bit:
- KSZ87xx: Reg 4, Bit 1 - if 1, max frame size is 1532; if 0 - 1514
- KSZ88xx: Reg 4, Bit 1 - if 1, max frame size is 1514; if 0 - 1532
Since the code was telling "... SW_LEGAL_PACKET_DISABLE, true)", I
assume, the idea was to set max frame size to 1532.
With this patch, by setting MTU size 1500, both switch series will be
configured to the 1532 frame limit.
This patch was tested on KSZ8873.

Apparently, the slcan's tx_work is freed while being scheduled. While
slcan_netdev_close() (netdev side) calls flush_work(&sl->tx_work),
slcan_close() (tty side) does not. So when the netdev is never set UP,
but the tty is stuffed with bytes and forced to wakeup write, the work
is scheduled, but never flushed.
So add an additional flush_work() to slcan_close() to be sure the work
is flushed under all circumstances.
The Fixes commit below moved flush_work() from slcan_close() to
slcan_netdev_close(). What was the rationale behind it? Maybe we can
drop the one in slcan_netdev_close()?
I see the same pattern in can327. So it perhaps needs the very same fix.

We currently have some complicated code in sfp_probe() which gets the
I2C bus depending on whether the sfp node is DT or ACPI, and we use
completely separate lookup functions.
This could do with being in a separate function to make the code more
readable, so move it to a new function, sfp_i2c_get(). We can also use
fwnode_find_reference() to lookup the I2C bus fwnode before then
decending into fwnode-type specific parsing.
A future cleanup would be to move the fwnode-type specific parsing into
the i2c layer, which is where it really should be.

Some drivers and NICs don't handle this properly resulting in an
interface reset or worse.
This issue was introduced by the removal of an unconditional skb pull in
the tx path to improve performance. Fix this without reintroducing the
pull by setting up grant copy ops for as many slots as needed to reach
the XEN_NETBACK_TX_COPY_LEN size. Adjust the rest of the code to handle

There is no need in hiding returned ASO WQE type by providing void*,
use the real type instead. Do it together with zeroing that memory,
so ASO WQE will be ready to use immediately.

Currently lan966x, doesn't allow to run PTP over interfaces that are
part of the bridge. The reason is when the lan966x was receiving a
PTP frame (regardless if L2/IPv4/IPv6) the HW it would flood this
frame.
Now that it is possible to add VCAP rules to the HW, such to trap these
frames to the CPU, it is possible to run PTP also over interfaces that
are part of the bridge.

Add the function vcap_rule_get_key_u32 which allows to get the value and
the mask of a key that exist on the rule. If the key doesn't exist,
it would return error.

Add the function vcap_mod_rule which allows to update an existing rule
in the vcap. It is required for the rule to exist in the vcap to be able
to modify it.

Add function vcap_get_rule which returns a rule based on the internal
rule id.
The entire functionality of reading and decoding the rule from the VCAP
was inside vcap_api_debugfs file. So move the entire implementation in
vcap_api as this is used also by vcap_get_rule.

There is warning report about of_node refcount leak
while probing mdio device:
OF: ERROR: memory leak, expected refcount 1 instead of 2,
of_node_get()/of_node_put() unbalanced - destroy cset entry:
attach overlay node /spi/soc@0/mdio@710700c0/ethernet@4
In of_mdiobus_register_device(), we increase fwnode refcount
by fwnode_handle_get() before associating the of_node with
mdio device, but it has never been decreased in normal path.
Since that, in mdio_device_release(), it needs to call
fwnode_handle_put() in addition instead of calling kfree()
directly.
After above, just calling mdio_device_free() in the error handle
path of of_mdiobus_register_device() is enough to keep the
refcount balanced.
